Comparison of the Spatial Variability of C- and L-Band Remotely Sensed Soil Moisture

원격측정 토양수분자료, (C-band 측정치 vs. L-band 측정치)의 공간변화도 비교

The spatial variability of the L- and C- band large scale remotely sensed soil moisture data, obtained during tire Southern Great Plain 1999 (SGP'99), was characterized. The results demonstrate that soil moisture data using L-band show the break in statistical symmetry (multiscaling behavior) with the variation of scale of observation, which is similar to that of the soil property such as sand content. Also, soil moisture data using C-band show single scaling behavior with the variation of scale of observation, which Is similar to that of the vegetation condition.
